The A-TEC H3 Suppressor represents the evolution of Norwegian suppressor engineering, succeeding the renowned H2 series with improved internal geometry, optimised gas flow, and high-efficiency sound attenuation. Engineered for high-exertion backcountry hunting and target disciplines, this modular over-barrel silencer delivers up to 30–35 dB(C) of noise reduction while keeping overall rifle length and weight tightly controlled.

• Modular 3-Stage Architecture: Allows users to quickly add or subtract baffle modules to customise overall length, weight, and sound attenuation to suit dense bush-stalking or open alpine environments.
• Hybrid Stainless Steel Blast Chamber: Incorporates a heavy-duty stainless steel first-stage blast chamber that acts as an internal muzzle brake, trapping high-pressure combustion gases and shielding the alloy baffles from throat erosion.
• Reflex Over-Barrel Configuration: Telescopes 80 mm rearward over the barrel while adding just 150 mm to the muzzle, pulling mass back toward the receiver to preserve a rifle's natural handling and pointability.
• A-LOCK Mini Mount Integration: Compatible with A-TEC’s A-LOCK system, enabling rapid attachment/detachment with a secure 60-degree twist, or configurable for traditional direct-thread mounting.
• MIL-STD-1474D Sound Testing Standard: Tested against stringent military sound testing standards to deliver verified, repeatable decibel reduction across standard and magnum cartridges.
• Free-Floating Rear Profile: The internal over-barrel sleeve is designed to float clear of the barrel contour, preventing contact interference and preserving rifle harmonics for sub-MOA performance.
